The book tells the story of the activists who fought for women’s right to vote and how close the vote to ratify the 19th Amendment really was. Their struggle has resonated through history in the civil rights movement of the ’50s and ’60s and in Clinton’s own ultimately unsuccessful presidential run in 2016.

"At the heart of democracy lies the ballot box, and Elaine Weiss’ unforgettable book tells the story of the female leaders who — in the face of towering economic, racial and political opposition — fought for and won American women’s right to vote. Unfolding over six weeks in the summer of 1920, The Woman’s Hour is both a page-turning drama and an inspiration for everyone, young and old, male and female, in these perilous times. So much could have gone wrong, but these American women would not take no for an answer: their triumph is our legacy to guard and emulate," Clinton said in a statement.

Clinton will be involved in the search for a writer, director and cast. The adaptation is being conceived as a limited series or movie for a premium cable network or streaming service.
